Mud Dauber nests are typically found around the outside of our homes attached to walls, under the eaves, and inside garages and other exterior buildings. These nests are made out of mud. Mud Daubers in general are not very dangerous, though they do sting. When abandoned, their nests are available as new homes for other insects and wasps that might take up residence in them when they are no longer in use. If you notice these empty nests around be sure to knock them down so they do not attract other insects to the area. Not sure if they have been abandoned? Look for holes in the nest. When the Mud Daubers leave their nest they come out, creating holes. While they are inside of their nest you will not see any holes. Call Elite Pest and Termite Control if you would like us to come and remove these nests.
